Unreal Tournament Cheats
Cheat codes are entered through the system command console that can be activated by pressing the tilde (~) key on your keyboard while the game is running. Once the console is active, type in the cheat codes you wish to use along with any additional data required by that code.
The cheat codes for Unreal Tournament are the same as the cheats for the original Unreal, with one major exception. You must now type IAMTHEONE at the console to unlock cheat mode before any of the other codes will work.
Once this has been done, you can type in any of the normal unreal cheats at the console and they should work just fine.
